The Book of Habakkuk is the eighth book of the 12 minor prophets of the Hebrew Bible. It is attributed to the prophet Habakkuk, and was probably composed in the late 7th century BCE. A copy of chapters 1 and 2 (of 3) is included in the Habakkuk Commentary, found among the Dead Sea Scrolls.
Chapters 1-2 are a dialog between Yahweh and the prophet. The central message, that "the just shall live by his faith" (2:4), plays an important rule in Christian thought. It is used in the Epistle to the Romans 1:17, Galatians 3:11, and the Epistle to the Hebrews 10:38 as the starting point of the concept of faith. Chapter 3 may be an independent addition, now recognized as a liturgical piece, but was possibly written by the same author as chapters 1 and 2.
